https://bugzilla.kernel.org/show_bug.cgi?id=65561 --- Comment #9 from Jidong Xiao <jidong.xiao@xxxxxxxxx> --- Hi, Paolo, It seems that Gleb's patch commit 03617c188f41eeeb4223c919ee7e66e5a114f2c6 "KVM: VMX: mark unusable segment as nonpresent" fixed a similar problem like this, look at this: https://bugzilla.redhat.com/show_bug.cgi?id=854983, Even though they are triggered by different reasons, they both cause the "hardware error 0x80000021" issue. So I feel that patch could also fix this single step issue.
